Some of our most common questions about solar components.
Here are the most common questions and answers to solar products and solar configurations.
All our products are sold without installation services included except if it states otherwise on the product. We supply installers and the public with affordable solar components. But, we can assist with installations if required by our recommended solar installer contractors where required.
We can provide you with solar installers in Gauteng and Western Cape. We make use of solar installer contractors who conducts all our residential solar installations for us.
It depends. If you want to go completely off the grid, you will save 100% on all your electrical expenses and be completely independent from Eskom. If you install a smaller solar panel kit, you can also reduce your electricity bill. It all depends on how many devices will be powered from solar and how many devices will remain on the grid. Either way, you can save up to 50% on average by converting to solar panels or even 100% when you fully go off the grid.
You can save up to 100% with hot water needs in your home by using a solar geyser. Depending on the size and the specific solar geyser and if you’re not going to use an electrical element, you can achieve this very easily. For the average home, you can save 45% on your electricity just by installing a solar geyser.
An electrical geyser can add up to 45% of your home’s overall electrical bill. We offer affordable solar geysers which is a much better option to install than the standard electrical geyser. It is a small investment but in the long run, the solar geyser basically pays for itself while you save money on your electricity bills.
- The most popular battery type for solar solutions in South Africa, is the flooded lead-acid batteries. They’ve been tried and tested and they do a great job of keeping your power going. Flood-Acid batteries would require maintenance. You will need to regularly inspect the water levels inside of the battery and also equalize the batteries about every 90 days.
- The battery storage options are mostly dependent on your budget.
- We would advise for everyone to invest in lithium-ion batteries as they offer great warranties and also excellent performance. Unfortunately, lithium-ion batteries are expensive.
- We also recommend sealed lead-acid AGM (Absorbed Glass Mat) batteries because they also offer great performance and does not come with such a hefty price tag as lithium-ion batteries does but still are more expensive than flooded lead-acid batteries. AGM batteries does not require all the maintenance and is basically maintenance free. AGM batteries has no off gassing or equalizing and you don’t have to check water levels. You install an AGM battery and you just kind of forgets about them.
- But there is not a one size fits all type of battery. Every system or solar setup requires a specific battery storage solution with specific battery types meeting your needs and your budget.
- You can choose a battery depending on how much work you’re willing to do for battery maintenance versus the cost related for the battery you want to install.
We offer backup battery kits, off-grid solar kits, grid-tied solar kits, and hybrid solar kits. It all depends on what you require. If you need to be independent of the utility grid or, save money by feeding into the grid and lastly, having the best of both worlds. Unfortunately, in South Africa, grid-tied systems for feeding electricity into the grid, are not available in every region across the country.
The total cost of solar panel kits depends on how large the home is, how many people live inside the home and how the people use energy. There is not a one size fits all solar panel system that fits everyone available. Solar Panel kits can start from R20000 up to millions of Rands, depending on how much power you require and how much you’re willing to invest.
The simple answer to this question, 20 years. This is a standard warranty period for the majority of solar panels on the market today. Solar panel warranties cover physical defects in solar panels for about 10 to 25 years. There are also certain warranties that guarantee a specific amount of power output, which is also, generally, for 25 years. Certain solar panel warranties will guarantee that the solar panels will function at a minimum efficiency of 80% or more. This is at the end of the 25 years. Basically, the decrease of solar panel efficiencies is less than 1% each year.
You might have to look into replacing your inverter in about 15 to 25 years. This depend on the type of inverter and if it is a quality inverter or not. Inverter warranties range from 1 to 25 years depending on the manufacturer and how good inverter it is.
Depending on how you use your batteries and the type of battery, batteries will typically need replacement in 3 to 15 years. Lead-acid batteries can last 1 to 5 years depending on their usage and if they stay in their temperature range and has not been discharged completely for too many cycles. However, lithium-ion batteries can last for an average of up to 15 years and some even longer if maintained properly.
It is basically, using 1000watts of power or electricity in a period of an hour. If you power a 100watt light bulb for one hour, you are basically using 100watt hours. If you power the 100watt light bulb for 10 hours, you’re at a 1000watts per hour or 1 kilowatt per hour. A hairdryer is running at 1000watts, if you power it for one hour, that will consume 1 kilowatt per hour or (kWh). All electrical appliances have different electricity ratings and how many watts they will consume every hour. Wattage multiply the amount of hours will give you the kWh per hour.
